well, firewalls or proxies are not an issue here, since the I'm
working within my company Intranet, so I should have any port
available.
On the other hand, I admit my ignorance about browser timeout. I
didn't know about this other aspect. What's the default value? and (of
course) is there any way to change it? After all, this timeout could
affect my "hidden" refresh as well if I set my refresh rate too large,
coudn't it?
